Abstract: An improved, hand actuatable pump assembly. A stem and piston assembly extend into a valve body. The piston sealingly engages the wall of the valve body and together they define a pressure chamber therebelow. The piston seals a discharge passageway in the stem. As the pump assembly is primed, air in the pressure chamber escapes through the discharge passageway. When the pump is ready for use, the force of hydraulic pressure below the piston opens communication between the pressure chamber and passageway. When the piston nears the end of the stroke, it is mechanically held open to complete dispensing. At all times, a positive seal between the piston and the valve body wall is maintained to prevent passage of the contents of the pressure chamber therebetween, thereby to minimize sticking and clogging of the pump assembly.

Abstract: A dispensing pump for application to a product container includes an elongated housing having a recess in a sidewall thereof and a flexible bulbous diaphragm seated over the recess for a trigger-type actuation as the housing is gripped in the manner of a handle. A variable volume pump chamber is defined by the diaphragm together with the recess, and an inlet passage is provided in the housing through which the product passes from the container into the recess. The diaphragm has an annular inner skirt for closing the inlet passage in response to axial deformation of the diaphragm, as well as intermediate and outer annular skirts. The intermediate skirt has a lower free edge portion normally covering a discharge port in the housing which communicates with the pump housing, and the outer skirt has a lower free edge portion normally covering a vent port in the housing which communicates with the atmosphere.
